3 Claims.

This invention relates to cleaners for conveyers and has for the primaryobject the provision of a simple and inexpensive device of thischaracter which may be readily adapted to a conveyer for automaticallyremoving materials which may adhere to the conveying means of saidconveyer as the means nears the discharge of the conveyer, obviating thecustomary practice of manually removing such material from the conveyingmeans and which frequently requires stopping of the conveyer and theloss of time and r the manual power required for the cleaning operation.

With these and other objects in view, this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which Figure 1is a fragmentary plan view showing the discharge end of a conventionalconveyer equipped with a cleaner constructed in accordance with myinvention.

Figure 2 is a sectional View taken on the line 22 of Figure 1.

Figure 3 is a fragmentary sectional view showing the means of retainingthe cleaner in an operative position to be engaged by the conveyingmeans as the latter nears the discharge end of the conveyer.

Figure 4 is a side elevation illustrating the cleaner.

Referring in detail to the drawings, the numeral l indicates aconventional type of conveyer wherein the discharge end is indicated bythe character 2. The conveyer has a conveying means of the endless type,the conveying means including sprocket chains 3 mounted on a sprocketwheel and equipped with flights 4. The sprocket wheels or gears aresecured to shafts 5 journaled to the framework of the. conveyer. Theflights cooperate with the framework of the conveyer for movingmaterials from the receiving end of the conveyer to the discharge endand when such materials are of an absorbent nature and contain moisturefrequently adhere to the flights and comparatively large masses fail todischarge from the conveyer so that after operation over a period oftime the conveyer becomes clogged necessitating stopping of the conveyerin order that the flights be manually cleaned from 1 the materialsadhering thereto, requiring loss of time and a large expenditure ofmanual effort.

vmounted to the flights by brackets (Ci. 1Ei8229) In order to overcomethis objection to conveyers.

my invention whenv adapted thereto will automatioallyclean each flightof the conveying means as it passes the discharge end of the conveyer.

My invention is adapted to the shaft 5 of the conveying means which islocated adjacent the discharge end of the conveyer and consists of ascraper 6 in the form of a blade having a scraping edge 1 and itsopposite edge cut away and to which are secured journals 8 receivingsaid shaft 5. The scraper 6 due to the journals 8 turns free of theshaft. Suitable stop collars ii are applied to the shaft for limitingthe endwise movement'of the scraper. The normal operative position ofthe scraper or blade is shown in full lines in Figure 2 and isreleasablysupported in this position by spring arms it! secured tobraces ll of the conveyer frame. The scraper or blade maintains thisposition until engaged by a flight and as the flight advances towardsthe discharge end of the conveyer the scraping edge I moves over theface of the flight removing materials which may adhere thereto so thatwhen the flight passes the discharge end it is clean of any material.The scraper or blade continues to follow the flight until said flightmoves away from said blade or scraper on its return run of the conveyer.The blade or scraper being journaled on the shaft 5 then gravitates intoengagement with the spring arms in where it is retained in the operativeposition to engage the next flight.

The spring arms iii are provided with spaced shoulders l5 and theshoulders of each arm cooperate in defining a notch in which the bladeor scraper seats when moving into operative position. The blade orscraper remains in the seats of the arms until positive force is appliedthereto by a flight coming in contact therewith.

In some instances the flights of the conveying means are equipped withguide rollers 22 being it. The brackets are secured to the flights bybolts and in order that the blade or scraper will not catch into thebolts a notch M is provided in the scraping edge I of the blade orscraper.

While I have described my invention used in connection with a conveyerof a specific c:n-

struction, it is to'be understood that the invcnporting shaft for saidconveying means located adjacent the discharge end of the conveyer, ablade journaled to said shaft and movable about the latter when engagedby a flight, and means temporarily retaining the blade in a position tocontact the flight as the latter nears the discharge end and moved oversaid flight with frictional contact therewith to remove foreign matteradhering to the flight.

2. In combination with a conveyer having an endless conveying meansincluding flights and a supporting shaft located adjacent the dischargeend of said conveyer, a blade journaled on said shaft and adapted torotate 'on said shaft when engaged by a flight for the purpose ofremoving materials adhering to the flight and permitting said flight topass the blade on its return run of the conveyer, and spring meansreleasably retaining the blade in a position to be engaged by a flightas it nears the discharge end.

3. In combination with a conveyer having an endless conveying meansincluding flights and a supporting shaftv located adjacent the dischargeend of said conveyer, a blade journaled on said shaft and adapted torotate on said shaft when engaged by a flight for the purpose ofremoving materials adhering to the flight and permitting 10 MYRL N.PENNY.
